Hi.

Code repeat several times. Why predefined variables not update inside "while"?

Thanks.

You probably have to use RefreshRates()
 
I've used it and does not work

What does that mean ? Show your code, and some logs to demonstrate your issue.
  
if ((Open[1]>Close[1]) && (RefreshRates()) && (hour ==TimeHour(TimeLocal())-1))
By including it in the condition its value is true, but not update Open[] and Close[]
 
Jusyer:

With the new mql4, if the condition Open[1]>Close[1] is false, the RefreshRates will never be executed. Don't include RefreshRates() in an if condition.

See this topic MetaTrader 4 Build 600 with Updated MQL4 Language and Market of Applications Released :

Shortened conditions check is now used in logical operations, unlike the old MQL4 version where all expressions have been calculated and the check has been performed afterwards. Suppose there is a check of two conditions with the use of logical AND 

  if(condition1 && condition2)
    {
     // some block of operations
    }
If condition1 expression is false, calculation of condition2 expression is not performed, as false && true result is still equal to false.
